One of the most popular exercises for strengthening the abdominal muscles is the crunch. Your core muscular group includes the abdominal muscles, which are the goal of the abdominal crunch.
How to properly execute crunches:
# 1
Lie on your back with your knees bent, feet flat on the floor, and your heels about 12–18 inches from your hips.
# 2
Without arching your lower back, put your hands behind your head and bring your shoulder blades together. Throughout, maintain the same position of your arms. Maintain your head in alignment with your spine as you raise yourself up, but give yourself permission to bend slightly so that your chin approaches your chest.
# 3
Upward Phase: Breathe out, tighten your core and abdominal muscles, flex your chin slightly toward your chest, and gradually curl your torso toward your thighs. Pulling your rib cage into your pelvis should be the main goal of the exercise (the neck should remain relaxed while the chin is tucked toward the neck).
Your lower back, tailbone, and feet should always be in touch with the mat. Until your upper back is raised off the mat, keep curling up. Maintain this position for a short while.
# 4
Phase Downward: Take a deep breath and slowly lower your torso back toward the mat while maintaining contact with the mat with your feet, tailbone, and low back.
A few notes :
Avoid putting your hands behind your head when performing abdominal crunches. This makes it difficult to isolate the abdominal muscles and increases the danger of harm to your neck.
To avoid putting too much strain on your low back, proper form is crucial. People typically execute this exercise too quickly and use their hip flexors to help with the upward phase.
This method should be avoided because it causes the pelvis to tilt anteriorly, which puts more strain on the low back.
The exercise should concentrate on bringing the rib cage and pelvis closer together while maintaining a relaxed neck and shoulders because the abdominals connect these two bodily sections.
